In gram-negative bacteria, the cell wall is thin and releases the dye readily when washed with an alcohol or acetone solution. Cytoplasm-The cytoplasm, or protoplasm, of bacterial cells is where the functions for cell growth, metabolism, and replication are carried out.
Function of the Amygdala. 1  Such spectacular demonstrations may be misleading. Stimulation of the amygdala sometimes triggers violence, but apparently it does not always or even typically trigger violence. 2  When the amygdala is damaged in humans, they lose their sensitivity to stimuli associated with strong emotions.
Yet, these people can still experience (feel) âfear.â In other words, the amygdala is an important part of the circuit that allows the brain to detect and respond to threats but is not necessary to feel âfear.â. Brain imaging studies of healthy humans (people without brain damage) suggest something similar.
